Abstract

The invention belongs to the technical field of coatings, and particularly relates to a silver ion long-acting sterilization wall coating and a preparation method thereof. The invention relates to a silver ion long-acting sterilization wall coating, which is prepared from the following raw materials: electrolytic silver water, an active group-containing monomer, a surfactant and a filler. According to the prepared silver ion long-acting sterilization wall coating, under the condition that the specific electrolytic silver water concentration is required, the silver ions in the prepared wall coating do not easily fall off, the stability is high, and the long-acting sterilization effect is guaranteed. The silver ion long-acting sterilizing wall coating prepared by the invention can well inhibit wall mildewing, especially aspergillus niger, and also can ensure that the wall coating is used at a low temperature, so that the use environment and the application value of the coating are expanded.

Description

technical field [0001] The invention belongs to the technical field of coatings, and more specifically relates to a silver ion long-acting bactericidal wall coating and a preparation method thereof. Background technique [0002] With the rapid development of the construction industry and the improvement of people's living standards, the requirements for wall coatings are becoming more and more diverse, including not only the requirements for the color of the coating, but also the improvement of the performance of the coating, the environmental protection of the coating, and the Human health and other aspects of the requirements. [0003] Chinese patent publication number is that CN111040598A discloses a kind of green antibacterial wall body paint, and its preparation raw material comprises: waterborne polyurethane, diatomite, antibacterial agent, stabilizer, leveling agent, calcium carbonate and defoamer, mentioned in the open patent that adopts The antibacterial agent is i...
